title: [Endoscopic and fluoroscopic pyeloureterotomy for ureteropelvic junction obstruction and ureteral stricture].
abstract: Endoscopic or fluoroscopic pyeloureterotomy was performed in a total of 32 patients (34 ureters) with ureteropelvic junction obstruction (UPJO) or ureteral stricture from March 1985. Cold incision was performed, using a flexible knife over a guidewire, endoscopically on 23 ureters and fluoroscopically on 11 ureters. The mean operation time was 98.9 +/- 48.3 minutes. Twenty-five (74%) of the 34 ureters showed relief of subjective symptoms, normalized urinalysis and radiographical improvement of hydronephrosis with a mean follow-up period of 11.7 +/- 10.0 months (range: 3-43). The clinical results by etiology were as follows: primary UPJO, 13/16 (81%); secondary UPJO, 4/4 (100%); ureteral stricture, 6/7 (85%); obliteration of ureteral implantation, 2/7 (29%). No major complication was noted with this endourological technique. This endourological technique might be clinically useful for the treatment of UPJO and ureteral strictures.
